PATENT JAMES A. TAYLOR, OF LIMA, INDIANA.

ROAD-SCRAPER AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 570,885, dated November3, 1896.

Application tiled March 5, 1896. Serial No. 581.997. (No model.) i

To all whom, it may concern.-

Be it known that I, JAMES A. TAYLOR, a citizen of the United States, anda resident of Lima, La Grange county, State of Indiana, have inventedcertain new and useful Improvements in Road-Scrapers and Carriers, (CaseC and mypreferred manner of carrying out the invention is set forth inthe fol lowing full, clear, and exact description, terminating withclaims particularlyspecifying t-he novelty.

This invention relates to road-Scrapers and carriers, and moreespecially to that class thereof known as self-loading carts and theobject of the same is to produce improvements in the details ofconstruction of devices of this character.

To this end the invention consists in a roadscraper constructedsubstantially as hereinafter described and claimed and as shown in theaccompanying drawings.

Reference is made to United States Patents No. 552,936, dated January14, 1896, and No. 555,270, dated February 25, 1896. In these patents areshown details of construction somewhat similar to those set forth below,but no claim is made in the present case to anything covered by theclaims in the patents hitherto issued.

Referring to the accompanying drawings, Figure l is an elevation takenfrom the left side of the machine complete, showing the same as carryingthree scoops or Scrapers, the forward one of which (lettered S) 'isillustrated in the act of scraping or taking up earth, the second one ofwhich (lettered C) is shown as at a carry, and the rearmost one of which(lettered D) is illustrated as in a dumped position. (The remainingviews omit the arch carrying the seat, as well as the front wheels.)Fig. 2 is a similar View and with the parts in the same positions, buttaken from the left side of the machine at a point just inside the leftside bar of the framework, and thus showing certain parts in section.Fig. 3 is a plan view of the machine Vshown as going in the oppositedirection and as in the views above. Fig. 5 is a cross-section of thescraper C, taken on the line-5 5 of Fig. 3. Fig. 6 is a perspectivedetail of a modiiied form of the arch. Fig. 7 is a perspect-ive detailshowing a modified form of the rear locking device. Fig. 8 is a planView of the front axle and hounds. Fig. 9 is a per spective detailshowing one of the blocks and its pivoted catch, which forms the bearingfor the stub-shaft on the scoop.

In the said drawings the main framework comprises right and leftlongitudinal side bars R and L, suitably connected at proper intervalsand supported by the rear axle A, carrying main wheels at itsextremities, and having at their front ends arches cmi pon which ismounted the drivers seat d.

F is the front axle, carrying at its extremi ties the forward mainwheels and connected at its center by a king-bolt and fth-wheel f withsimilar parts at the forward ends of the arches a, as will beunderstood.

II are hounds attached to the front axle,

and T is the tongue, preferably bolted, as at ,any other suitableframework may be substivtuted for that shown and described.

The machine herein illustrated has three scoops or Scrapers.mounted'between the side bars of the framework, and it is myintentionto so construct it; but it will be obvious that each machine could carrya greater or less number of Scrapers, according to the amount of work tobe done, the roughness of the earth at the point being treated, thestrength of the team, and other conditions. Although I have not shownit, there is preferably a narrow platform extending along one or bothsides of the framework and on which stands the operator who is tomanipulate the levers described below, while the drivers sole duty is toco'n-` trol the team, drive tothe proper points and at proper times, andstop the machine when it is desired to dump.

I might here add that the parts described below are of any desiredsizes, proportions, and materials, and the exact shape of the parts isimmaterial, except that they should conform with the constructionsrecited in the claims, as will be understood.

In all cases the letter S designates a scoop or scraper (or the partsthereof) which is scraping or in the act of taking up earth. C is onethat is at carry, by which I mean that when in this position the earthso taken up can be transported bodily by the machine,

and D one that is dumped and held dumped or in the act of being dumped,so as to discharge the contents of the scoop at the dumping-point.

Secured to and rising from the side bars of theframe are blocks 1, whichhave cut in their upper ends transverse notches 2, which form bearings,and these blocks are also longitudinallynotched, as at 3. In said notch3, at one side of the bearing 2, is pivoted on a transverse pin -t acatch 5, adapted to swing down into the notch 3 and close the upper endof the bearing 2, the free end of this catch being held in place by apin or other removable device G.

7 is a stron g arch (a modification of which is shown in Fig. G) whosecenter stands normally across and above the scoop and whose ends 3 turndownward and are provided with outwardly-proj ectin g stub-shafts 9,which are j ournaled in said bearings 2. This arch may be made in one ormore pieces, as desired, and its center may be bowed slightly upward, asshown in Fig. 3 at S, or it may be straight, as seen in Fig. G.

10 is the main lever, secured rigidly, as by bolts, across one end ofthe arch. In the drawings it is shown at the left end when viewed fromabove, as in Fig. 3, although it will be obvious that it could be placedat the right end and all the levers be on this side of the machine. Thislever is held firmly to the arch by a brace 11, attached to the leverand extending from its body obliquely across the arch, bowed slightlyupward, and rigidly connected with a slotted arm 12, which projectsforward from the other end of the arch the same as does the forward endof the lever 10, which latter is also slotted. livoted in the front endof each. slotted arm is a link 13, whose body moves th rough' a guide,hereinafter described, and whose lower end is pivoted to the side of thescoop 14. IIence when the handle of the lever is drawn to the rear thescoop is raised from the scraping position S to the carry position C,and during such movement the upright portions 3 of the arch pass overthe supporting-pivots 9, by which it will be seen that the weight of thescoop can be very easily raised, and after being raised is firmly heldin the bearings.

15 are tongues projecting to the rear and downward from the rear end ofthe right slotted arm 12 and from the lever 10, the tips of thesetongues engaging sockets 16 in the sides of the scoop when the latter isat carry.

17 are other tongues, which may be fastened to and project upward fromthe sides of the scoop and which are adapted to engage sockets 18 in theright tongue 15 and in the lever 10 when the scoop is at carry. Thesetongues and sockets will firmly prevent lateral or longitudinalmovements of the scoop both while at carry and while being dumped orafter having been dumped, because in the act of dumping the scoop doesnot change its position with relation to the arch and lever.

20 is a curved and preferably metallic sheet located just forward ofeach scoop when the latter is in its carrying position and preferablyhaving its extremities 2O bent to the rear, the function of this sheetbeing to guard and prevent the exit of the dirt from the scoop at thistime. This sheet is supported by rods 21, which may have slotted ends22, connected adjustably by bolts 23 with the side bars of the frame, orwhich may have their ends held by such bolts adjustably beneath clips25, carried by said side bars. There is one guard for each scoop, asWill be clear. Y

Projecting inward from the lower ends of the upright portions 8 of eacharch are pins 30, which engage slots 31 in the forward ends of aU-shaped bail 32, whose side bars are pivoted, as at 33, within theframework and whose rear member 34 stands across in rear of the scoopand has rising therefrom two guide-lingers 35.

36 are hooks projecting rearward and downward from the upper rearcorners of the scoop and adapted to pass over this bail j ust insidesaid guide-iingers, and 37 are lugs located just beneath these hooks andin position to pass under the transverse portion of this bail when thescoop is in it-s scraping position. In the act of dumping the scoop andwhen it is turned around the pivots 9 these hooks 36 rise off the bail34E and the lugs 37 pass by such bail, while at carry the hooks restupon the bail and support the rear end of the scoop, and in moving thescoop to a scraping position (as described below) it slides bodily tothe rear, so that the lugs 37 pass under the bail and prevent the rearend of the scoop from accidentally rising or being thrust fartherrearward, while at this time the pins 30 raise the slotted front ends 32of the bail and cause the rear side 34E of the latter to descendslightly, as will be seen in the drawings at S in Fig. 2. A slightmodification of this construction is shown in Fig. 7, wherein theguidelingers, hooks, and lugs are dispensed with, and in their place issubstituted the following construction: The rear portion 34 of the bailcarries adjacent each rear corner of the scoop an upright finger 35',and the corner of the scoop has a horizontal loop 37 projecting to therear and a hook 36' beneath it. This view shows in full lines the scoopin a scraping position,.at which time the bail is drawn tightly into thehook 36 and the nger 35 projects obliquely through the loop 37', so asto prevent the rear end of the scoop from rising. In dotted lines theparts are shown with the scoop at a carry, at which time the bail IOOTIO

IZO

has passed out of the hook 36' and the finger 35' rises straight upwardthrough the loop 37', from which it may be bodily raised in the act ofdumping.

The numeral 40 designates a long hook projecting forward from the rearof the scoop at its center, and this hook engages a catch 41, carried atthe center of the arch 7.

42 is a thumb-lever carried by the main lever, and 43 is a rod forswinging the tip of this hookout of said catch. It' the hook engages theright side of the catch, as seen in Fig. 3 at C, the rod 43 operates apivoted pawl 44, so that pressure on the thumb-lever 42 will move thetip of the hook to the right; but if the hook engages the left side ofthe catch the construction will be as shown in Fig. 6, wherein the innerend of the rod 43 has a slot 46 sliding over a pin on the catch and hasa lip 47 at its free end so located as to disengage the hook from theleft side of the catch. It will be clear that either Yconstruction maybe employed without departing from the general principle. Vhen the scoopis raised from a scraping position to a carry, the catch moves backwarduntil it e11- gages the hook 40. This holds the scoop from falling, andwhen the same is dumped by the main lever the catch, by engaging thehook, causes the rear end of the scoop to be raised bodily around thepivots 9. v has been moved to its completely-dumped position, a hook 48,carried by the side bar of the frame, engages the main lever 10 toprevent a return movement of the scoop, and this hook is disengaged fromthe lever when it is desired to throw the scoop back to a carry.

At each side of the scoop or scraper 14, near the front end thereof, issecured a hook 50, and connected therewith is a strap 51, eX- tendinglongitudinally of and slightly remote from the scraper, so as to form aguide for the link 13, as'above mentioned. Said hook is adapted toengage with another hook 52, (best seen in Fig. 4 at 8,) whose body isL- shaped and is pivoted at its angle at 53 to the side bar of theframe, its upright bar being pivoted to a slide 54, which is adapted tomove longitudinally through the slot 3 in the block 1. This slide has-apin 55, engaged by a cam 56, which is secured to the upright portion ofthe end 8 of the arch 7, the construction being` such that when thescoop is moved from a scraping position to a carry the cam pushes on thepin and shoves the slide forward, whereby the uprightarm of the hook 52is pushed forward and the hook itself is caused to rise, this movementlifting the hook 50 and assisting in the eleva-tion of the mouth of thescoop. Vhen the latter is turned on its pivots 9 for the purpose ofdumping, the hooks 50 and 52 do not engage each other.

57 is a spring carried by the side bar of the framework and pressing thehook and slidev in proper direction, so that when the scoop is movedfrom a carry to the scrapingposition the spring pushes the slide backwith its pin Vhen the scoop.

in contact with the cam and permits the proper movement of the hook 52to( engage it with the hook 50 on the scoop'. The latter on reaching itslowermost position, ready for taking up earth, is therefore held by theengagement ot' the hooks with each other. slight modification of thisconstruction is shown in Fig. 2 at D, wherein the hook 52, althoughpivoted at 53', is not of L shape, but has an arm 53" connected with theslide 54 in about the manner shown, the operation of this constructionbeing practically the same as above described.

A team is hitched to the tongue, the driver takes his seat, and themachine is driven to the point where it is desired to take up earth. Oneor more of the Scrapers are then lowered to the scraping position andthe machine driven forward, so that loose earth from the surface of theground will be taken into the several scoops, which may be thus lowered.When each scoop or scraper is filled, the attendant moves the lever 10backward and the scraper is drawn to a carrying position wherein theguard lwill prevent the earth from running out of the scoop. All of thescoops having been iilled, the machine is driven to the'dump', and whenit has arrived at the proper point the assistant raises the main levers1Q to.

dump the scoops, as will be clear. The hooks 48 hold the scoops indumped position, after which themachine is driven back to the placewhere the scraping is to be done, and the entire operation is repeated.This is done by disengaging the hook 48 from each lever and throwing thelatter to the rear, so as to bring the empty scraper again to a carry.Then the thumb-lever 42 is manipulated to disenupper ends formingbearings and also provided withlongitudinal notches in their upper ends,a catch pivoted at one extremity in the latter notch at one side of thebearing and having its body passing across the bearing, and a pinholding the tip of thecatch removably in place; of an arch havingstubshafts journaled in said bearings, a leverconnected with said arch,a scoop also connected with the arch, and means for holding the scoop inany one of several positions, as and for the purpose set forth.
